I recently upgraded from a wheel on trainer (Elite Novo) to a direct drive trainer (Elite Zumo), on my old trainer in ERG mode the power matching to the target was exactly on point all the way though the wrok out, with my new trainer the power is up and down by 30 Watts or more at time at some points, I can feel the resistance changes so I no it is definitely being controlled by the software but it looks like I’m riding in ERG mode (spiking up and down around the target power).
Is this what all direct drive trainers are like or do I have a faulty one?
I haven’t changed any settings in trainerroad software and I’m using the same set up, I have tried it with ANT+ and Bluetooth and it is a bit smoother with Bluetooth but it makes the rides a lot more difficult, fluctuating from 230 to 290 Watts when I’m supposed to be doing 260 is really annoying and hard to maintain.
Some trainers such as the Wahoo Kickr track the Target Power more closely than other trainers, but seeing some variation is totally normal depending on your specific model. +/- 30 watts is certainly a bit dramatic, but see if you can decrease that variation by focusing on smoothing your pedal stroke as much as possible.
You may also want to apply Power Smoothing within the TrainerRoad app to apply a rolling average to the data for a more useful power reading. 3 seconds is a good place to start, and you can increase from there if you want more smoothing, or decrease it if you want a faster response.
Give that a shot, and if you still feel that your trainer is not behaving correctly, reach out to our Support Team at email@example.com and they can take a closer look.
my power smoothing is set to 3 seconds already and that is what it was at before, i will try increasing it to 5 seconds and see if it is any better.
i think my cadence is about as smooth as it can be to be honest, my preferred cadence is 93rpm and i can hold that easily without focusing but i did actively focus to try and keep it from effecting my power but it didn’t help, in the 15 minute efforts i was doing my cadence didn’t fluctuate from 92 or 93 apart from when i stood for a minute and the power was still fluctuating.
I knew smoothing just effected the display, and not actual behavior of the trainer. But I assumed the display included the chart and the power digit display. Thx for clarifying it’s just the power digits.
This is not excessively variable behavior. In fact, this is exactly what I would expect from a majority of the trainers on the market. There a few trainers that appear smoother, but the reality is that no one’s pedal stroke is perfect and will naturally experience some variation. Your trainer is simply showing that variation with a higher level of accuracy .
Maybe this is normal and I’m just used to having it easy with a lower quality trainer, it just doesn’t feel right because u can really feel the power going up and down like a wave when my cadence is really smooth, it feels like the trainer is fighting me like inexperienced people do when they try erg mode for the first time, like I have my head down pedalling constantly and then I feel the resistance increase so I look up at the screen and I see the power go from around 260 to about 280 or more and then after a few seconds I feel it drop off again and it feels really easy and it then shows I’m doing around 230 Watts.
Hmm, that is peculiar. If you haven’t already, I would recommend reaching out to our Support Team at firstname.lastname@example.org so that they can look at your logs and see if they can shine some light on the situation.
I had exactly the same when i moved from my wheel elite qubo to my Tacx flux. From what i’ve read the qubo was not as accurate which lead to all my graphs being perfectly smooth ( almost like it was not reporting a change within +/- 5 watts )
